Arrays of electrodes operating at identical potentials

When each electrode in the array is operating at the same potential, the overall response of the electrode array depends on two parameters the density of the electrode distribution and the relative dimensions of the electrodes with regard to the thickness of the diffusion layer, 5, developing at each active element of the array. In other words, for a given array geometry, its electrochemical behavior will be strongly dependent on the time scale of the electrochemical perturbation (21, 26). 

2 Arrays of electrodes operating in generator/collector mode 

Conformal mapping techniques often allow explicit analytical equations to be formulated for steady-state currents observed at electrode arrays in a generator/collector mode (48, 52, 53, 114). The steady-state regime is experimentally the most useful regime in these operating conditions. Under steady-state conditions, the enhanced cross-talk between electrodes leads to a reduced diffusional flux of species toward the solution as time proceeds. A steady-state regime is rapidly reached in the generator/collector mode in
